Shortly after Eternia was taken, it was terraformed to produce millions upon millions of new Gems, acting as the Diamonds’ agents to restore order to the universe. And Inevitably, both by design and by chance, these two forces would soon clash.
The war between the Horde and the Gems would send shockwaves to every corner of the known universe. Even planets not directly touched by either army would feel its ramifications. Factions would ally themselves with either one, reasoning that the other was worse, or form their own side to destroy both. But in the end, this conflict between two Great Computers would outlast any of these.
